Arbitrum One

Top coin — the largest coin's share of this chain's stablecoin supply. HHI — Herfindahl-Hirschman Index, the sum of squared percentage shares on a 0–10,000 scale, the same definition published for the market-wide concentration series. Both are computed over every coin with supply on the chain, not only those listed below. A chain's concentration measure describes only its stablecoin mix. It does not indicate the security of the chain or the soundness of the issuers represented on it.

Coins with at least $1M of supply on this chain, ranked by that supply. 38 further coins hold smaller balances here and are counted in the concentration figures above but not listed.
